Sower and Ulamog lists like the one I posted had a bunch of Top 8s in the past two months. I think it's a contender for the best Eldrazi deck easily
Excellent. The 10 post build is much more resilient to wasteland than typical Eldrazi lists. It's much harder to disrupt its mana production and has easier time recovering from Temple or Eye or Post getting Wastelanded. I refer you to my original post about the advantages of playing 24 sol lands in combating wastelands here...

Yes I played all those matchups, Lands, Sneak Attack, Grixis Tempo, Death and Taxes. It is favorable against all of them.
